They have come in handy on occasion on my E46 m3. Although I JUST encountered the washers the other day in my e92 and those things are out of control. Shot fluid all over the hood lol.. Guess I'll make sure my headlights are off next time.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
